Cheers LOM appreciated [emoji1303]
Any idea what screw head size Is holding the photomultiplier in place?
My estimate is 2 mm (just eyeballing) - 3 mm is 1/8th inch and I am using a lot of 3 mm aluminum in building my hoth blaster. Those heads look thinner than this, but 1 mm is probably too small
No, these screw heads are much larger! I measure 4 mm diameter head in my 3D file.
Looking at all the images I'm beginning to think that the top center of the cylinder is a separate piece added on.
Possibly from inside or from the bottom.
Look at the seam edges, there appear to be rough gaps.
The screen caps (post 222) look almost jagged.
The piece is almost "floating" at the top with the rest hollow for electronics and greeblies.
The pic of a page from a book also shows threading in the holes (possibly from the greeblies).
Was this likely to have been made in the UK at Elstree, I'm guessing so with all the talk of the linear slider knobs. So bearing that in mind would it be more likely that they were using something like a 6BA or 8BA roundhead screws instead of metric stuff.
I was thinking the same thing. It looks like its a separate piece.

I do wonder as well
this looks like some good ol’ fashioned prop finagling to me

Something weird is going on next to the slider knob on our side. almost like theres a wire and some gray thing poking up
oh my god, thats a funny optical illusion lolThat's the inside you're seeing. The top is only thin. I wonder what's keeping the slider knobs up in place.
I am more and more convinced that the holes in the base were not drilled but molded in the original part. In my 3D model I found that the inner ridges in the bottom have a draft angle and that the holes are intentionally passing through these surfaces. It's so perfect that I don't think it could have been done by hand and it wouldn't have made sense. Also: they are perfectly equally divided 4x in a circle. And the outer rows are 12 degrees on both sides of the center row.
